Situated not only near the South Pole, but also at 3300 meters above sea level, Concordia is one of only three inland bases inhabited all year around. Given the altitude, the crew is subjected to long exposure of hypoxia and during the winter they go through 100 days of straight darkness, when temperatures can reach –80°C and wind can blow up to 300 km/h.Antarctica seen by ESA astronaut Alexander Gerst from Space Station.

In many ways, the crew in Concordia are space pioneers as much as astronauts: they live for eight months in complete isolation. They are confined to a small space and share with people they did not know before. Their circadian rhythms are completely altered as they go through 100 days of straight darkness ...
